I knew this show was about a high school for exceptionally gifted boys but I didn't know they were all so "close". The main character, Keita, gets accepted even though he's average and things go wrong fast. Most kids accept him and fight for his attention but others don't want him there. His next door roommate takes him under his wing but because I don't like spoiling things, I'll just say he's hiding something. I watched this in Japanese with English subs and it made sense. There is no mature content at all or even kissing (until a certain part) so I'm not sure why the mature rating. Fun show with some twists. I had to watch it all in one sitting.
